Job Shop Scheduling Software That Shops Don't Abandon
Job shop scheduling software has a dirty secret: it's the most-abandoned module in the category. Owners report giving up on their system's scheduler a decade ago; reviews of major systems say the scheduling module 'just plain doesn't work.' Meanwhile the whiteboard — which costs supervisors around 45 minutes a day — keeps working, because it never lies about its confidence.
The failure is structural. Finite-capacity optimization needs data hygiene (perfect run times, real-time status) that a 6-person shop will never maintain. Garbage in, confidently-wrong schedule out.
What actually works: the reactive board
The best spec for small-shop scheduling was written by a shop owner in a forum thread: 'machine goes down, big rush order comes in, material is delayed — the system reacts and suggests a new schedule.' Reaction, not optimization: a priority queue per machine, drag-and-drop, and an honest answer to 'if I move this hot job to the front, which promise dates break?'
Add TV mode — every job by machine on the shop television, red when late, yellow when close — and you've replaced the whiteboard with something that updates itself from floor scans. Shops already jury-rig exactly this with legacy software and a flatscreen; it should be a first-class feature.
The scheduling questions that matter
Can two people be in the schedule at once? (One notorious legacy system locks scheduling to a single user.) Does the board update from floor activity, or does someone re-type reality every morning? What happens to promise dates when you expedite? And can the guy at the saw see what's next without asking?
Traveler ships the reactive board with TV mode and an expedite blast-radius preview — and deliberately does not ship a finite-capacity optimizer.

▸What's the best scheduling method for a job shop?
For high-mix low-volume under ~20 people: a priority queue per work center with honest promise dates beats finite-capacity optimization, because it survives imperfect data and reacts to expedites without pretending to precision it doesn't have.
▸Do I need machine monitoring for scheduling?
No. Scan-based op start/complete from the floor is enough to keep a board live. Machine monitoring is a later refinement, not a prerequisite.
